Another shorter explanation might be from Bill's August 1987 HP Journal article "An Evolutionary RPN Calculator for Technical Professionals".

Also, read "HP41 / HP48 Transitions", Chapter 2. from the same horse (Bill Wickes). As this issue was one of the obstacles to many 41 users transitioning to RPL, Bill covers it in good detail and is probably the best coverage on the topic. By coincidence, I was just re-reading this while on vacation last week, the explanation of the subtleties involved is excellent.

Both books are included in the MoHPC document set, here:

As you're new here, I strongly recommend you get this collection. There are more than 1700 documents/manuals/books/guides/etc. and nearly every topic that comes up eventually leads to pointers to docs in the set.
